(NM-AIST, 2021-07)Rabies is a disease which is most transmitted to humans through infected domestic dog bites. The disease is preventable through mass dog vaccination (MDV) or timely access to Postexposure Prophylaxis (PEP) injections ... -
Dynamics of nicotine across the soil–tobacco plant interface is dependent on agro-ecology, nitrogen source, and rooting depth
(Elsevier, 2019-12)Tobacco (Nicotiana tabacum L.) is the primary nicotine producing plant through its root system (Steppuhn et al., 2004; Shoji et al., 2008). It produces nicotine to as high as 4% of its leaf content compared with potato, ... -
Ecological effects of selected invasive plants and their nature based management approaches
(NM-AIST, 2017-12)Biological invasions are one of the major threats to most ecosystems as they often suppress native plant species. This suppressive effect is usually costly and irreversible hence calling for effective management strategies ... -
